## Q30 key (Crypto Tracing)

1. The mixed 12-bitcoin pool was two-thirds separate and one-third marital because 8 units were premarital and 4 were bought with marital funds. Missed: commingling is treated as either total forfeiture or total separate ownership.
2. The 3-bitcoin sale retained that proportion: 2 bitcoin of value was separate and 1 marital, but the proceeds were spent on ordinary marital expenses and generate no reimbursement. The remaining 9 bitcoin likewise equal 6 separate and 3 marital units. Missed: the sale changes the character of what remained or creates a reimbursement rule not supplied.
3. Exchanging 6 of the 9 bitcoin for 90 ether carries the two-thirds/one-third ratio into the ether. The known holdings of 3 bitcoin and 90 ether remain two-thirds separate and one-third marital despite the cold-wallet transfer. Missed: a wallet transfer or asset exchange resets classification.
4. Known value is 3 times $50,000 plus 90 times $3,000, or $420,000. Separate value is $280,000; marital value is $140,000; Mira's one-half share is $70,000. Missed: tracing arithmetic is wrong by six figures.
5. The second 40 ether is worth $120,000 and is presumptively marital because it arrived during marriage and Evan has not traced a gift. If marital, Mira's ordinary half is $60,000, making her total crypto share $130,000. Missed: an unsupported gift claim removes the wallet from division.
6. If intentional concealment is proved, the 20 percent surcharge on the $120,000 concealed marital value is $24,000, making Mira's potential recovery from the crypto division and surcharge $154,000. Missed: surcharge is applied to all crypto or omitted from the concealed asset.
7. Demand exchange statements, KYC and account records, transaction hashes, source-wallet history, tax lots, donor communications, the brother's wallet records and testimony, and device or backup records linking Evan to the wallet. Seek a neutral forensic order if not produced. Missed: final settlement fixes a classification while the decisive source evidence is withheld.
8. Reject the $50,000 global crypto settlement. Preserve a conditional branch only after discovery: $70,000 on known marital assets plus the second-wallet division and surcharge depending on tracing and intent. Missed: Mira accepts less than her undisputed half of known marital crypto.
